Marketing Consultant: The Strategy I Wish I Knew 15 Years Ago

By Zach Schleien

Learn what a marketing consultant actually does, how they differ from agencies, and the specific strategic shifts that doubled close rates and landed the NYT.

TL;DR: Summary of Marketing Consulting Insights

• A marketing consultant provides high-level strategy, objective audits, and execution roadmaps to help businesses scale revenue without the overhead of a full agency.
• They differ from agencies by focusing on "the why" and "the how-to" rather than just providing "done-for-you" services on a retainer.
• Hiring a consultant is the right move when your growth has plateaued, your internal team lacks a specific skill set, or you need to build a high-ticket sales funnel from scratch.

A marketing consultant is a professional who provides expert advice and strategy to help businesses improve their brand positioning, customer acquisition, and overall revenue growth. Unlike an agency that might just manage your social media, a consultant embeds themselves in your business to identify gaps in your funnel and build systems that you eventually own.

What exactly does a marketing consultant do on a daily basis?

A marketing consultant identifies growth bottlenecks and builds strategic playbooks that bridge the gap between where a company is and where it needs to be. On a daily basis, they audit existing campaigns, design high-converting funnels, and coach internal teams on execution.

Marketing consulting isn't about giving generic advice. It is about building assets. A typical day for a consultant might include:

• Funnel Audits: Reviewing every step from the first ad click to the final sales call to find where leads are dropping off.
• Offer Design: Restructuring pricing tiers (like the economy, business, and first-class "airplane" model) to maximize profit.
• Copywriting: Drafting VSL (Video Sales Letter) scripts or cold email sequences that actually get replies.
• Coaching: Watching recorded sales calls to help reps improve their close rates from 20% to 40%.

When I ran Filteroff, I had to become my own consultant. I let go of my sales agencies because the cash was running out and the reps were underperforming. I spent my days watching my own call recordings and tweaking the script until the close rate nearly doubled within 30 days. That is what a consultant does: they find what is broken and fix it with a repeatable system.

How much does it cost to hire a marketing consultant?

The cost of a marketing consultant varies based on expertise, but you can typically expect to pay between $150 and $500 per hour, or project-based fees ranging from $5,000 to $25,000+ for a full strategy build. High-level fractional CMOs often work on a monthly retainer basis that scales with the complexity of the business.

• Hourly Rates: Best for quick audits or specific "pick your brain" sessions.
• Project-Based: Best for building a specific asset, like a webinar funnel or a PR launch campaign.
• Retainer-Based: Best for ongoing strategic leadership where the consultant acts as a part-time department head.

Think of it like this: instead of hiring a full-time marketing director for $150,000 a year, you pay a consultant a fraction of that to install the system. Once the system works, your lower-cost team members can run it. It is often cheaper to pay for the "how-to" than to pay for someone's full-time salary while they "figure it out" on your dime.

What is the difference between a marketing agency and a consultant?

The main difference is that a marketing agency is an execution partner that provides "done-for-you" services, while a marketing consultant is a strategic partner who builds the roadmap and teaches you how to own the growth. An agency wants to keep you on a retainer; a consultant wants to install a system that works without them.

I have hired both. At Filteroff, I hired a Facebook ads agency and an influencer recruitment agency. Both underperformed. The mistake I made was delegating the responsibility before I understood the job. I now recommend founders pay a consultant to teach them the skill over a month or two. Knowing when to hire a fractional CMO vs an agency can save you thousands in wasted retainers.

How do I know if my business is ready for a consultant?

Your business is ready for a marketing consultant when you have a proven product-market fit but your growth has plateaued, or when you are preparing to launch a new high-ticket offer. If you are still "guessing" your growth, you need a strategist, not just another pair of hands.

• The plateau: Your ads are running, but your cost per acquisition (CPA) is climbing.
• The skill gap: You need to build a high-ticket call funnel but your team only knows low-ticket e-commerce.
• The transition: You are moving from founder-led sales to hiring your first closer.

If you are currently building a business on the side, you might not be ready for a high-priced consultant yet. You can still learn the fundamentals yourself. Balancing a side hustle with a 9-to-5 requires building these systems on nights and weekends first.

What ROI should I expect from hiring a marketing expert?

You should expect a marketing consultant to provide a clear return on investment through decreased acquisition costs, increased lead quality, and higher sales conversion rates. A successful engagement should pay for itself by optimizing the math of your business.

For example, I worked with a matchmaking client who left her 9-to-5 to go full-time. We built her funnel, practice calls, and sales scripts together. Within three weeks, she brought in $22,000, more than she ever made in a month at her old job. That is the ROI of a consultant: they don't just "do marketing," they unlock revenue.

Another example is my work with a personal trainer. He had 55 old leads he had never texted. By building a simple reactivation system, he converted 4 new clients in a single day at $150 per session. That one move is on track to be worth $30,000.

I share more about these shifts in my weekly newsletter at https://newsletter.zachschleien.com.

What are the different types of marketing consultants?

Marketing consultants specialize in different levers of growth. Choosing the right one depends on which part of your funnel is broken.

1. Fractional CMO: Provides high-level strategic leadership and manages the entire marketing department.
2. Growth Consultant: Focuses on rapid experimentation, lead generation, and improving lead quality.
3. PR Consultant: Focuses on earned media and brand authority. I landed 200+ features without an agency using a system of angles and targeting.
4. Sales & Funnel Consultant: Specializes in high-ticket conversion, sales scripts, and call funnels.

What questions should I ask to vet a marketing consultant?

To vet a marketing consultant, ask for specific "receipts" of their work. A real operator will talk about numbers and failed experiments, while a theorist will talk about "brand awareness" and "synergy."

1. "Can you show me a funnel you built and the conversion data behind it?" Look for specific metrics like a 2.3x ROAS or a 15% landing page conversion rate.
2. "What is a time a strategy failed, and how did you pivot?" Real marketing is about pivoting. I pivoted Filteroff four times before finding the high-ticket matchmaking model that led to acquisition.
3. "Do you do the work, or do you teach my team to do the work?" You want a consultant who builds assets you own, not someone who creates a "dev dependency."
4. "How do you stay current with AI tools?" Marketing is moving faster than ever. If they aren't using AI tools to compress research, they are costing you time.

One story, three news cycles: The power of a strategic approach

The difference between a consultant and a technician is how they view a single asset. A technician sees a task; a consultant sees a "cascade."

In March 2020, my dad caught COVID and barely avoided a ventilator. While he was in his hospital bed, he wrote his story down. When he came home, I didn't just "post it." I sat at the kitchen table and acted as his strategist.

I emailed writers, not the outlets, but the people. I sent pitches to about 70 journalists who covered that beat. On April 9, 2020, his op-ed ran in the New York Times. But the consultant mindset means the story doesn't end there. We rode that one story through three news cycles:

• The personal story: Fox News, Good Morning America, and CNN.
• The pediatric health angle: USA Today and Newsday.
• The school reopening debate: The Washington Post.

One story, three news cycles. That is what a marketing consultant does. They take one piece of value and multiply it across the entire landscape.

Conclusion: Stop guessing and start building

Hiring a marketing consultant is a bet on the systems of your business. It is about moving from "marketing by accident" to "growth by design." Whether you are auditing your sales calls to double your close rate or pitching the New York Times to build authority, the goal is the same: building a business that compounds.

If you are ready to stop guessing and want to see how a strategic growth engine can work for your company, let's talk about building your roadmap.

FAQ

How long does a typical consulting engagement last? Most strategic projects last between 3 and 6 months. This allows enough time to audit the current state, build the new assets, and test the results against real data.

Do consultants also execute the marketing tasks? It depends on the agreement. Some consultants are "pure strategy," while others (like a fractional CMO) might manage freelancers or agencies to ensure the execution matches the strategy.

Can a marketing consultant help with PR? Yes, but ensure they have real experience landing earned media. Look for someone who understands that you pitch people, not outlets and can show you the actual pitches that worked.

What is the best way to work with a consultant on a budget? Hire them for a one-time "Strategy Intensive." Pay them for a high-value day of work where they map out your entire year, and then have your internal team execute that map.
